No, that's helpful, thank you.
I think the problem is I’m 28 chapters into what should be 34 chapters, so I’m close enough to the end that I keep getting tempted back. I’ll suddenly realise something makes more sense now, then go back and add a bit, cut a bit, fiddle with a bit.
I have also learned that if I can’t fix a passage in about an hour, it probably needs cutting, which is brutal but usually true.
Anyway, I’ll suffer on. Harry does, so I suppose I have to. Three chapters being public is enough for now.
